老师说I will can you when coming back,可以换成when I come back,不可以换成while coming back.
1.为什么?
2.come在这里可以用现在进行时?
3.能详讲这里的知识点吗?状语是进行时?我只是初中生、
对不起,是I will call you when coming back.既然是非延续性,为什么有coming?
那请问可以用when I am coming back吗?

一：这里主要是while,when 的区别,when,while都可解释为“当…时候”,用来引导时间状语从句,它们的区别如下：
1、while 意为 during the time that“在……期间”,表达一个“时间段”,不能表达“时间点”,从句的动词只限于持续性动词.例如：
One day while he was shopping in the supermarket, he saw his ex-wife with a man.
一天,他在超市购物时,他看到了他的前妻和一个男子在一起.
Strike while the iron is hot.
趁热打铁.
2、when 意为 at the time that“在…时”,多指“时间点”,例如：
When he returned from work, his wife was cooking.
他下班回家时,他的妻子正在做饭.
另外补充一下as的用法
as 意为 at the same time that“正当……”或“与……同时”,它兼指“时间点”和“时间段”,从句的动词既可是短暂性动词,也可是持续性动词.例如：
The door bell rang as we were having breakfast.
正当我们吃饭的时候,门铃响了.
As the time went on,the weather got worse and worse.
随着时间的推移,天气越来越糟.
归纳：
总的说来,3者的功能区别大体可作如下描述：
while 为主句动作的发生划定一个时间的范围；
as 为主句动作的发生提供一个伴随的动作；
二：come是非持续性动词,所以不能用while；
三：状语的时态,主要看主语时态和主从句谓语动词先后发生关系

老师说I will can you when coming back,可以换成when I come back,不可以换 I will tell you when he will come back I miss you very much,when will you come back I’llcall you when he comes back可以换成when he comes back I’ll c 英文翻译：I will leave when you come back -when will you come back?-i will come back A.at a time B.all i can’t tell you.when will jim come back?的同义句 When will you come back? I don't know when he _(come)back.when he _(come)back,I will Can you tell me when will he come back可以而Can you tell me wh 单词填空 I will ___you when I come back. When can I back home
